EVAPORATOR.

IEECFCj-LT forming part of Letters Patent No. 331,867, dated Becember 8, 1885.

Application filed March 9.0, 1885: Serial No. 159,561. (No model.)

.T0 @ZZ inkom z'f may concern.-

Be it known that I, LEVEN `\V. COOPER, of Sinitlis Mills, in the county of Henderson and State of Kentucky, have invented certain new and useful Improvements in Evaporators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appei'tains to inakc and use the saine.

My invention relates to an improvement in eval'iorators, and particularly to the class of evaporators designed for the evaporation of saccliaiinc substances.

rlhe object of iny invention is to provide iinproved means whereby the senin which invariabl y fornis on thc. surface during the process of boiling the Sirup niay be conveniently and effectually reinoved.

A further object is to provide nieaiis of the above character which shall be siniple and economical in construction and durable and eiiicicnt in use, and with these ends in view niy invention consists in the certain features of construction and combinations of parts, as will be hereinafter fully described, and pointed out in the claiins.

The accompanying drawing is a view in perspective of niy invention.

A represents the pan, provided with the longitiidiiially-extending partitions B and the horizontallyextending central partition, C, as shown, thus forming suitable compartments, c, for the reception of the sirup. To one side of the pan is attached a tub or other recept-acle, D, to the bottoni of which are connected the siriip-convcying tubes or pipes E, one of which is connected Withtlie extreme apartment, and the other connects directly with thel apartment nearest the tub.

@ne end ci' the evaporator is provided with a revolving shaft having the paddles or skiininers F. f Liese paddles are preferably broad and perforated, as shown. rlhe paddles are rigidly secured to the cranked shaft G, whi ch in turn is journaled in the vertical standards H, foi-ined integral with or secured tothe side fi'anies of the evaporator. To the cranked ends of the arins G are loosely mounted the pitinan-rods I, the opposite ends ot' the rods being inoiinted on opposite ends ofthe cranked rod J, which is suitablyjournaled to the fraine of the evaporator, preferably about the center thereof. One. end of t-he crank-rod J is provided Witli a suitable handle, K, by means of which the rod .l is operated and the skimmer set in inotion. The partit-ion C is provided ivith a gate, L, for the purpose of regulating the discharge of the siriip to the rear section of the pan.

The forward end of the evaporator is provided with a trough, M, having the open end N, through which the senin is conveyed to any suitable receptacle. The trough M is provided centrally on its inner face with inwardly-projecting lug or aiin O, against which the skimnier F is adapted to strike and pass when rotated, thus causing the skiininer to vibrate and jar, whereby the matter which has accumulated thereon will be shaken off and consequently fall into the trough, as described.

The rear end of the pan is provided with a suitable outlet pipe or tube, l?, by means of which the sirup after being sufficiently treated is conveyed as desired.

' Having described the construction of my device, I will proceed to describe the iniiiner in which the saine is operated.

rEhe sirup or juice is emptied into the tub D, from which it is conveyed by means of the pipes into the side compartments, c. lThe sirnp tlows toward the ibrivard 'end of the evaporator. It then naturally seeks the cent-ral coinpartinent, Q. sirup will have engendered a considerable ainount of scum. The skimmer or paddle F is then rotated in the direction of the trough, and as the paddle is provided with perforations on its end siinilar to a sieve the clear juice will pei'colate tlierethroiigh,and the seu in and other heavy substances will cling to the face of the paddle until the saine is forced against and past the lug 0, which process will cause the paddle to vibrate, thus shaking the senin and other substances free froni the paddle into the trough. The sirup continues to tloiv into the eoinpartnient Q, from which its iloW into the rear section of the pan is regulated by incans oi' the gate L.

I claim as new, and desire to secure by Letters Patent, is-

l. The combination, with an evaporator, of a cranked shaft, a series of perforated paddles or skiininers secured to said shaft, and devices,
